useful Improvements in Brake-Hangers, of

which the following is a specification.

. My present invention relates to improvements in brake hangers and aims to provide asimple economical, strong and durable construction which will avoid all danger of the brake beams dropping on the rails due to breakage of parts or working out of keys.

The invention includes the novel features of construction and arrangement and combination of partshereinafter described and particularly defined by the appended claims, the invention being illustrated by the accompanying drawings, in which- Figure l is a front elevation ofa supporting lug and hanger embodying my invention, the brake-head and shoe being omitted.

Fig. 2 is a side elevation.

Figs. 3 and 4 are detail views illustrating the manner of inserting the hanger supports in the bracket.

Fig.5 is a side elevation ofone of the hanger supports.

Fig. 6 is a detached front view of the two hanger supports.

Fig. 7 is a section on line 77 of Fig. 5.

Fig. 8 is a section on line 8-8 of Fig. 5.

Fig. 8 is a detail of the locking pin.

Fig. 9 is a section on line 9 -9 of Fig. 1.

Figs. 10 and 11 are respectively a front view and side elevation of a modification.

Referring by reference characters to this drawing the numeral 12 designates a bracket designed to be secured in any suitable manner to the truck frame and provided with a pair of depending spaced lugs 12 having transverse circular passages or recesses 12 therethrough. 13 and 14 designate the hanger supporting memberswhich are provided near their upper ends with lateral cylindrical projections 13 and 14? designed to fit in the passages or recesses 12% and which are further provided in their lower parts with recesses 13 and 14 designed to receive the u per ends of the brake beam hanger 15 which is held therein by a pin 16 have invented certain new andin the manner hereinafter more particularly described.

The hanger supports are made in the two parts, 13 and 14, to enable them to be applied to the brackets and locked in position with the studs or projections pivotally supported in the openings or recesses 12 an to this end the member 13 is made with a lateral cut away portion or channel 13' which corresponds in width to the width of the upper end of the member 14. Thus after the member 13 has been inserted between the legs. 12 and moved laterally until its stud or projection 13 lies in the corresponding opening or recess or passage 12 and said member is allowed to drop or rest in vertical position, the member 14 is held in horizontal position or at right angles to member 13 and its upper end inserted in the transverse recess 13 until the stud 14 is in line with the corresponding recess or passage 12 Thereafter the member 14 is moved laterally away from the member 13 until Stud 14 is entered in said recess or passage 12, when said member 14 is allowed to drop or is swung into a position parallel with the member 13 bringing the upper end of member 14 out of line with the channel 13, thus holding the parts against any inward movement and automatically locking the studs in the recesses from which they cannot be removed without swinging one member into a position at right angles to the other. As the members are held in alinement by the hanger iron and connecting pin it will be seen thatv accidental disconnection of the hanger supports is eifectually r'evented.

The brake shoe hanger is preferably of endless or integral form and comprises parallel bars 15 and15 on each side of the brake head and hanger.

The bars 15 and 15 on each side are connected at their upper ends by an integral bend and the loops thus formed are inserted in the recesses 13 and 14 and are held therein by the locking'pin 16 inserted in a slot 16 formed in hanger supports 13 and 14. This latter has at one end an olfset portion or lug 1 6 and when the hanger is inserted in the position shown in dotted lines in Fig. 4 and the pin inserted in slot16 until the lug 16 alines with recess 13* the doc turning of the hanger downward from the horizontal will bring-the lug into the groove, locking the pin in position against accidental displacement.

The lower ends of hanger arms or bars 15 are connected by transverse bars 15 and 15, preferably integral with the hanger arms so that while I provide only a unitary hanger it is in effect a double hanger and therefore of maximum strength. The bottom ends or cross bars 15 and 15 are so made that a standard M. C. B. head can be used. The head is shown at 16, the brake shoe at 17 and the beam at 18, the full lines showing the position of the parts with a worn brake shoe pressed against the wheel, and the dotted lines with an unworn shoe out of contact with the wheel.

The cross bars of the hanger arms are pivotally engaged in the recesses in the head as clearly shown in Fig. 2 and one of the the shoe to keep the hanger ..in the end of the bolt.

.ber lt hasan annular channel 19 to receive hanger arms is provided with a lug 15 designed to contact with the back of the head in case the shoe should back off.

To remove the beam the shoes at both ends are removed and the beam tilted toward the wheels so that the tops of the heads will point toward the wheels allowing the cross bar 15 in the lower slot to be disengaged when the heads can be lifted up and backed out of the hanger.

The lower cross bar 15 is made of egg shape in cross section to engage the back of in rigid connection with the head.

An important function of my invention is to prevent brake shoes from being unevenly worn and therefore scrapped before being completely used up. As the hanger is rigidly connected to the head it follows that the hanger is always in the same position relative to the head, and as the hanger supports swing on a short radius the weight of the brakes alone will insure a quickand complete release of the brakes.

Instead of using a bracket with spaced lugs, I may use a bracket. with a single lugas shown at 12 in Fig. 10. In this event the hanger supporting members 18 and 14* are shaped at their upper ends to lie against the outer faces of the lug 12 and are provided with transverse holes to receive the holding pin 19. The member l3 has a lug w adapted to engage a side of the head on the bolt to prevent the latter from turning. The bolt having been passed through the member 13 and then through the aperture in the lug and having been brought into a depending position the member 14* is applied to the projecting .end of the bolt while in a hori zontal position or at right angles to member 13*, the key 20 having been first inserted through a transverse key receiving opening The head of memmembers to be connected the key and a passage 19 through which the key passes into the channel when the member 14: is at right angles to the member 13*. In all other positions the bolt is locked in position by the key and the key retained in place by the wall of the annular groove or channel.

In'the form shown in Figs. 10 and 11 the hangers are connected to the supports in the same manner as in the preceding form of the invention.

Having thus described my invention, what I claim is 1. In combination, a supporting bracket, a pair of hanger supports, means for pivotally connecting said supports to the bracket, said means operating to permit the to the bracket when said members are at angles to each other and being automatically locked by the alinement of the members, and .brake shoe hangers pivotally connected with said members.

2. In combination, a supporting bracket, a pair of hanger supports, means for pivot;- ally connecting said supports to the bracket, said means operating to permit the members to be connected to the bracket when said members are at angles to each other and being automatically locked by the alinement of the members, and brake supporting hangers connected to the lower ends of said supports and normally holding therm in alinement.

3. In combination, a supporting bracket, a pair of hanger supports, means for pivotally connecting said supports to the bracket, said means operating to permit the members to be connected to the bracket when said members are at angles to each 105 other and being automatically locked by the alinement of the members, said supports having recesses in their lower ends, U-shaped hanger arms having their bent portions inserted in said recesses, a key passing through 110 the supports and engaging said bends, and a brake shoe head supported from said hanger arms.

4. In combination, a supporting bracket,

a pair of hanger supports, means for pivot- 115 ally connecting said supports to the bracket, means operating to permit the members to be connected with the bracket when out of alinement and locking them thereto when alined, said members having recessed lower 120 ends, U-shaped hangers, seated in said recesses, and a pin passing through said supports and engaging the bends of:the hangers, said pin having a projection normally held by the hangers in one of the recesses 125 to lock the key in position. 7
